The Ford 6.0 STC HPOP Fitting Update Kit 4C3Z-9B246-F was the redesign of the high pressure oil pump for 2005 and newer Power Stroke diesel engines the "snap-to-connect" or STC fitting used to connect the high pressure oil pump to the oil supply branch tube has been problematic. The two piece fittings have a tendency to flex causing wear on the seal and the locking ring resulting in leaks and occasionally the complete separation of the fitting. When a leak occurs at this fitting, the engine may be difficult to start or may not start at all. Depending on the severity of the leak the engine may stall, sometimes abruptly and without warning.
